等の欠点がある。A small rotating blade (pulsator) is installed on the side of the washing tub.
The jet type, which rotates at high speed to spray the washing water in the tub, and the whirlpool type, which rotates rotating blades attached to the bottom of the washing tub at high speed to create a whirlpool in the washing water, can cause the laundry to be twisted and flow into the rotating blades. Because of this, (a) knitted fabrics are easier to stretch, (b) accessories such as buttons and hooks are easier to remove, and (→
(2) The ends of cuffs and collars are easy to tear, and (e) The ratio of the amount of washing water to the weight of the laundry (e) There are drawbacks such as a large ratio) and the need for a large amount of detergent.

洗濯槽１のほぼ中心部との間を往復運動する。To use the washing machine of this example with such a configuration,
First, as shown in FIG. 5, when the compression blade 9 moves to the inner wall of the washing tub 1 and is in a good open state, the laundry to be washed is placed in the net 38, and predetermined detergent and water are put into the washing tub 1. Next, when the motors 19 and 37 are turned on (not shown), the washing tub 1 is rotated by the rotating shaft 11. This K causes a swirling flow in the washing water in the washing tub 1. At the same time, the cam 30 rotates at a rotation speed v1 slightly higher than the rotation speed v2 of the rotating shaft 110. As a result, the cam 30Fi rotates at a speed ΔV corresponding to this rotational speed difference relative to the washing tub 1, and the cam follower 2
7 to swing the drive arm 26. The swinging of the drive arm 26 causes the support column 2Fi to reciprocate, and as shown in FIGS. Exercise.
洗濯槽１内の被洗物は、前記洗濯水の旋回流により洗濯

洗濯槽１の中心部に移動する。これにより被洗物は、従
来の洗濯機にないもみ洗いを受ける。The articles to be washed in the washing tub 1 are moved to the inner wall of the washing tub 1 by the swirling flow of the washing water, and moved to the center of the washing tub 1 by the compression action of the compression blades 9. As a result, the items to be washed receive a massage that is not provided in conventional washing machines.

流を生じさせるように構成することもできる。In the above embodiment, the washing tub itself is rotated as a means to generate a swirling flow in the washing water inside the washing tub. It is also possible to create a swirling flow in the washing water by doing so.
また洗濯槽の外部に洗濯槽内の洗濯水を循環させる水ポ
ンプを設け、このポンプの噴流により被洗物を洗濯槽の
中心部からその内壁の方へ移動させることもできる。Alternatively, a water pump for circulating the washing water in the washing tub may be provided outside the washing tub, and the jets of this pump may move the laundry from the center of the washing tub toward the inner wall thereof.

優れた効果がある。As described above, according to the present invention, by causing the compressed layer to reciprocate between the inner wall of the washing tub and the center of the washing tub while creating a swirling flow in the washing water in the washing tub, It can perform massage washing that is not seen in conventional electric washing machines, (a) the force is evenly applied to the items to be washed, so there is no partial damage to the fabric, and (b) the speed and compression of the swirling flow are excellent. By adjusting the reciprocating speed of the blades, it is possible to adopt a washing method according to the type of fabric and the degree of dirt, and if it is a textile product that can be washed with water, it can be washed even with a product that requires only one force. -→ By achieving a cleaning effect with a small washing tank, you can ultimately wash clothes in a short time with a small bath ratio and a small amount of washing! 2) By arranging a bag-like net inside the washing tub, there is an excellent effect that eliminates the need to use the net used in conventional washing machines.
